help wires everywhere!!

[74novajohn]

hello all,
I recently started rebuliding a dream car, but it is turning into a nightmare. The wiring for my 74 nova is all jacked up. thing are everywhere and no schematic will tell me what i need to know. I have no rebuld experiance but would love to learn, i am an eletrican( so i am a bit dissapointed that i can't get simple wiring problems corrected), so i know how to deal with schematics and eletricity. Well first off, what are the colors for the gauges ( fuel,batt,temp,oil pressure). they are all out and the back is just a "cluster fudge" of wires. no gauges were hooked up. if anyone can help me with the hook up instructon to these guages i'd really appriciate it. thanks
john

Hi John,

Welcome to Steve's Nova Site!

Well first off, what are the colors for the gauges ( fuel,batt,temp,oil pressure). they are all out and the back is just a "cluster fudge" of wires. no gauges were hooked up. if anyone can help me with the hook up instructon to these guages i'd really appriciate it.

I assume your car is equipped with the optional gauge package that is mounted near the front of the console. If that is the case, the factory wire sizes & colors are as follows:

20ga pink = +12V feed to fuel and temp gauge
20ga tan = sending unit connection to fuel gauge
20ga dark green = sending unit connection to temp gauge
20ga black = ground
14ga black & 14ga black w/dbl white stripe = batt gauge (ammeter)

The factory oil pressure gauge is mechanical so there aren't any wires connected to that.

The wiring diagram I have also shows a 20ga grey wire running down to the console and branching off (factory in-line splice) to the four bulbs that illuminate the gauges.
